π¨ AURORA ALERT π¨ β POTENTIAL FOR AURORA TONIGHT AND OVER THE COMING DAYS! πππ
Quick Aurora alert as of 00:05 BST, 6th September 2026.
π Potential for aurora tonight with currently negative Bz!
π Active east limb regions rotating into Earth-facing view!
π Potential glancing blow from C8.5 CME expected around 8th September!
π Minor G1 geomagnetic storm watch in place for 8th September!
Hi everyone! Just a quick aurora update. It has been a frustrating few weeks for aurora chasers, with plenty of solar activity but most of it directed away from Earth. However things are starting to look a little more promising!
RECENT SOLAR ACTIVITY
The Sun has been very active over the past few days, with multiple eruptions and CMEs from the east limb. While most of these have been directed away from Earth, the source regions are now beginning to rotate into Earth-facing view, which gives us hope for more Earth-directed activity over the coming week or two.
A C8.5 solar flare around AR 4524 on 5th September produced a CME that may be partially Earth-directed, with a potential glancing blow which is predicted to arrive around 8th September. Due to potential of this glancing blow, NOAA have issued a minor G1 geomagnetic storm watch for the 8th of September. We will keep you updated with any developments.
CURRENT STATS
We are currently seeing some elevated solar wind stats due to being within a high speed stream from a coronal hole that began to face Earth a few days ago. The most encouraging sign right now is a sustained negative (southward) Bz, which is the key ingredient needed for aurora to develop. Solar wind conditions are currently at a slightly elevated level and which is currently resulting in some aurora activity visible for those in Scotland and more Northern latitudes.
Solar wind speed is currently at fairly average levels of 355 km/s.
Density is currently at slightly elevated levels of 6.2 p/cm3.
The overall strength of the Interplanetary Magnetic Field (Bt) is steadily ramping up and is currently at a fairly elevated 8.5 nT.
The polarity of the IMF has been slightly negative hovering around -1 nT for a prolonged period of time now at but is currently sitting near neutral. Hopefully the Bz can drop further south and stay there allowing aurora to build.
EARTH WEATHER
Cloud cover is a mixed bag across the UK tonight with pockets of clear skies predicted throughout the night. The best opportunities for clear skies look like they will be in North-East Scotland and parts of North-East England. As always, weather forecasts aren't 100% accurate and the only way to be sure is to head out and check your northern horizon!
LUNAR CONDITIONS
Good news on the Moon front! The Moon is currently at around 20% illumination and does not rise until 00:42 BST, so lunar light pollution is relatively low tonight and with a large window of moonless skies. π
ASTRONOMICAL DARKNESS
We are now heading into autumn which means the nights are getting longer and darker skies are returning. True astronomical darkness is now falling earlier and lasting longer which is great news for aurora hunters as we head towards the equinox!
SUMMARY
To sum up, we have a sustained southward Bz right now which is the key ingredient for aurora development, with substorm activity already being detected. The main uncertainty is cloud cover across much of the UK. If you have clear skies to your north tonight, particularly in Scotland or northeast England it is definitely worth keeping an eye on your northern horizon! The coming days also look potentially interesting as those active regions rotate into view. Let's keep our fingers crossed! π€π
